Abstract
The present invention provides an ink composition for 3D printing based on a urea reaction that is applied as a liquid on a build platform, undergoes a phase change to a gelled solid in an applied state, and forms a 3D structure by being cured by cross-linking through the urea reaction with a curing agent ink sprayed onto a surface, and a 3D printing method using the same.
Claims19
An ink composition for subject ink applied to a 3D printing method in which a 3D structure is printed by cross-linking through a urea reaction between a subject ink and a hardener ink, wherein the ink composition for subject ink has a [Formula 2] structure below:
- wherein R1 and R2 are a hydrocarbon structure, and m is a repeating number of 1 or more.
